PORTABLE CI C L Rs rnnnivin'rAL T Bf To all whom it mdyooncem l1 Be itknown thatfI', GHARLES F PFALZ Gnar, a citizen of the United'States,residing I at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Portable Circular Sheet- Metal Tubs, ofwhich the following is a specification.

This invention relates to improvements in portable circular sheet-metal,tubs of the class that are, used for domestic laundry purposes. g Y

The larger sizes of these sheet-metal tubs are tapered from .the top'tothe bottom so they may be nested one into. another during storage andshipment, and frequently a sin gle nest will include from four to sixdozen tubs. which unless otherwise prevented will result in the tubsbecoming tightly wedged together. 7

The object therefore, of the invention is to provide an improvedhandle-device below the top-rini and on the tapered wall of the tub toengage the top rim of another tub into which the first tub is nested.

The invention is illustrated in the accompanying drawing, in which, I 7

Figures 1, 2 and 3 are end, side and bottom views. respectively of thebase-plate of the handle.

Fig. l, a side elevation of a broken portion of two sheet metal tubsnested and showing the handle device; 8

Fig. 5, is a vertical section of two sheetmetal tubs nested, the sectionbeing taken on the line 5-5 of Fig. 4. j The numeral 6, designates thecircular wall of. a tapered sheet-metal tub" having a suitable bottom(not shown), and an outward-turned top-rim 7 The said circular wall of atub is provided} ing in the tub-wall 6,, an outward ring-' shapedexpansion 9, which, vertically considered. alines with the tapered art6, of

the wall; and the external inverter shoulder 10, is formed by producingiii the tub-wall below said seat an outward expansion 11, \vl'iose uppercircumferential commences p c a was P te 1 Patented nee-9:19.19..llpplication filed August 17, 1915. Serial :No. @5319. '8

' at the innerinost part of theseat 8, ivliere 'there'is no outwardexpansion, and then extends downward at an inclination to "said the twolower flanges let; the three flanges have holes 16, and rivets 17, inthese holes secure the base-plate to the tub-wall 6. A loop handle 18,is bent sothat its two ends 19, enter at opposite sides 20, of the opening of the shell or concavo-convex part 15. This central shell part isapproximately T-shape; the two opposite sides 20, represent the topcross-bar of the T, and each side has an opening into which one of the.

ends 19, of the bent handle enters. At its middleand lower part thisshell has a downward-facing shoulder 21, which represents the post ofthe T; each side opening 20, has a down-curve 22, that merges into theshoulder 21, and said curves serve as strengthening braces for the saiddownward shoulder.

As already'stated the downward shoulder 21, on the: base plate of onetub serves to seat on the top-rim 7, of an exterior tub,

as shown in Figs. l and 5, and thereby vco actswith the structure thatincludes the said internal seat 8, and the said external invertedshoulder 10. I

The drop handle 18, ohm inner tub hangs pendant at the outer side :ofthe tub neXt below. When a drop handle is raised from the pendantposition its two arms come in contact with the two stop-shoulders 23,on"

thebase-plate adjoining the open sides 20.

When the handle is grasped to lift the vessel it will swing up until itsend 19, en-

gages the stop shoulder 23, at which time said handle will have alaterally projecting position and will be rigid because of the weightin'the vessel. By means of this construction two persons may grasp thetub handles and while carrying the tab the 131;

ter will be held against swaying or rocking on the handles consequentlyspilling of the contents will be avoided.

Having thus described my invention what I claim is, r V

The combination with a tub having a tapered wall with an annular toprim-edge, of a handle plate having two spaced-apart bottom flanges and atop flange with straight upper edge to seat under the rim edge of thetub-wall and said handle plate having a T-shaped bulge, the horizontalportion of Which bulge extends parallel with the top flange and thevertical portion of which bulge depends at a point between the twospaced bottom flanges-whereby the vertical portion of the bulge willextend outwardly with respect to the bottom flanges and form a stopshoulder, and a loop handle having its ends entering the opposite endsof the horizontal portion of the T-shaped bulge.

In testimony whereof I affix my signature in presence of two witnesses.
